9 Claims. (01. 24-33) My invention relates to a fastening means for invention shown in the accompanying drawing, fastening the abutting ends of a fabric belt or this reinforcement is in the form of a transverse apron by means of clips, known in the trade as rod about which the ends of the belt or apron a clipper fastener. to be joined are folded or wrapped in position to In fasteners of this type, clips are fastened into be engaged by the clips. 5

the ends of the belt or apron in spaced uniform Referring to the drawing, the abutting ends distances transversely of the belt, with their ends Hl and l l of the belt or apron to be fastened are projecting in the form of loops. The projecting wrapped about transverse rods l2 and I3 reloops of the clips of one belt or apron end or edge spectively. Clips M are then mounted at uni-- 10 are slightly offset from those of the opposite or formly spaced intervals lengthwise of the rod 10 abutting edge, so that they may be interleaved. A I2, and transverse of the belt or apron and simitransverse rod is then inserted in the manner of a lar clips l5 are arranged at equally spaced inpintle, thereby fastening the ends together tervals lengthwise of the rod 13.

During this forcing inward of the clips, at'these points and tending to tear them loose they are bent tightly against the rods l2 and from the fabric.

Means for fastening two sheet ends in a flexible fastener which comprises relatively rigid transverse reinforcements assembled therewith, one at each of said sheet ends to receive tensile stresses therefrom, looped clips extending from each of said ends toward the other end at spaced intervals and in interleaved arrangement and mounted to transmit longitudinal tensions to their respective reinforcements and a pintle pin extending through the interleaved loops to secure them in a hinged joint.

8. A fastening means comprising a substantial ly rigid transverse reinforcement, a sheet of flexible material having one end assembled with said reinforcement to receive tensile stresses therefrom and a series of looped clips secured to said sheet and reinforcement assembly at spaced intervals transversely of said sheet.

9. A fastening for securing two sheet ends in a flexible fastening which comprises substantially rigid transverse reinforcements, one assembled with each sheet end to receive tensile stresses therefrom, a series of looped clips, one of each series secured to said sheet and reinforcement assembly at spaced intervals transversely of said sheet with the projecting looped ends interleaved with those of the opposite sheet end and a pintle extending through said interleaved loops to form a hinge connection.
